FIELD

Embodiments of the invention relate to a detachable drone for monitoring a moving vessel. In particular, embodiments of the invention relate to a detachable drone to assist search and rescue in aviation and/or naval accidents.

BACKGROUND

Accidents in aviation are an unfortunate reality. For example, an airplane that goes missing or crashes is a tragedy that leaves the world wondering what fate the airplane and its passengers had. The loss of an airplane may make retrieval of flight recorders difficult, if not impossible, in some cases.

For example, the existing communications grid in extreme cases, such as this one, may not be sufficient to keep in contact with all of the airplanes at all times. Even in established areas, there is not sufficient bandwidth to monitor all of the flight data that an airplane's flight recorder collects. This vulnerability has a significant impact on the families who have lost loved ones and delays delivering closure to those families.

Similarly, naval vessels may suffer from similar issues in the event of an emergency at sea. Naval vessels have voyage data recorders, similar to flight recorders.

DETAILED DESCRIPTION

The descriptions of the various embodiments of the present invention have been presented for purposes of illustration, but are not intended to be exhaustive or limited to the embodiments disclosed. Many modifications and variations will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments. The terminology used herein was chosen to best explain the principles of the embodiments, the practical application or technical improvement over technologies found in the marketplace, or to enable others of ordinary skill in the art to understand the embodiments disclosed herein.

Embodiments provide a detachable drone that attaches (e.g., externally) to a moving vessel, monitors and collects data on the moving vessel (e.g., by monitoring sensors of the moving vessel), and assists in retrieval and delivery of the collected data in case the moving vessel is missing, has crashed, has sunk, etc. In particular, the detachable, self-moving drove automatically detaches from the moving vessel with the collected data. The collected data may then be used to determine what happened to the moving vessel.

With embodiments, the moving vessel may be a water-based vessel (e.g., a boat, a ship, a life raft, etc.), an air-based vessel (e.g., an airplane, another drone (such as a military drone), a space shuttle, etc.) or a land-based vessel (e.g., a bus, a car, a truck, motorcycle, etc.). The detachable drone may be attached directly to an external portion of the moving vessel (e.g., placed on outside of airplane) or be attached indirectly to the external portion of the moving vessel (e.g., coupled to the external portion of ship by a tow line).

FIG. 1 illustrates, in a block diagram, a computing environment in accordance with certain embodiments. A detachable drone 100 includes a computing device 110. The computing device 110 includes a data capture system 120 and storage 130. The data capture system 120 stores collected data 140 and beacon data 150 in the storage 130.

The detachable drone 100 is an autonomous and independent drone. The detachable drone 100 may also be described as an Unmanned Aerial Vehicle (UAV), which may be operated in a fully autonomous manner by the data capture system 120. That is, the detachable drone 100 is “self-moving” and may be autonomously moved by the data capture system 120.

The detachable drone 100 may be attached to a moving vessel, and, in response to certain triggers, the data capture system 120 automatically detaches the detachable drone 100 from the moving vessel. The moving vessel may be referred to as a host vessel for the detachable drone 100. With embodiments, the detachable drone 100 is attached to the exterior of the moving vessel (e.g., a conventional aircraft or boat). With embodiments, there are several ways that the detachable drone 100 may be detached/deployed, which all vary based on how the detachable drone 100 is housed. For example, for a water-based vessel (e.g., a ship), the detachable drone 100 may be connected by a tow line to the water-based vessel (so that the detachable drone 100 is already separate from the water-based vessel it is monitoring), in which case detachment of the detachable drone 100 involves cutting the tow line. As another example, for an air-based vessel (e.g., an airplane or a space shuttle), the detachable drone 100 may eject itself, release a parachute, and glide (via the parachute) back to the surface. In other embodiments, for an air-based vessel, the detachable drone 100 slowly lets loose on a line attached to the air-based vessel until stable, which the detachable drone 100 eventually cuts and flies with an option to eject more rapidly in case of severe emergencies.

Flight recorders and voyage data recorders are examples of “black boxes” as used herein. In certain embodiments, the data capture system 120 emulates a black box of a moving vessel by recording 1) data on various parameters continuously or periodically (several times per second) to preserve the recent history of the moving vessel; 2) sounds within and/or external to the moving vessel (e.g., within a cockpit of an airplane or an engine room of a ship); and 3) video feed within and/or external to the moving vessel. With embodiments, the data on the various parameters include measurements of vessel velocity, air pressure in the moving vessel, speed of the moving vessel, and weather conditions, and also readings from one or more (which may be pre-selected) of the moving vessel's sensors. For example, data on fuel levels, engine heat, landing gear, alerts of any kind (especially those that note potential malfunctions) are monitored and recorded.

With embodiments, the detachable drone 100 receives information identical to what is transmitted to one of the moving vessel's existing black boxes. In other embodiments, the detachable drone 100 may receive or retrieve information from a black box.

In embodiments, the detachable drone 100 with the data capture system 120 is separate from the black box and may autonomously act in the event of an emergency. In particular, rather than becoming a piece of the wreckage in case of a crash of the moving vessel, the data capture system 120 automatically detaches the detachable drone 100 from the moving vessel and delivers the detachable drone 100 to an accessible location, which may be pre-designated. The data capture system 120 may move (e.g., fly, roll, etc.) the detachable drone to the accessible location. With embodiments, the detachable drone 100 may move on land, move in water or move through the air. For example, the detachable drone 100 may report the status of, say a tank column, in the desert that has become stranded in some way. The detachable drone 100 may also sail, float (space or water), glide (parachute, un-propelled flight) or sink, as needed. Also, with embodiments, detachable drone 100 of a land-based vessel may drive to a pre-designated location. Moreover, with embodiments, the detachable drone 100 of an air-based vessel may navigate its flight to a pre-designated location (i.e., a specific landing zone or to a point on the air-based vessel's original flight path). With embodiments, the detachable drone 100 may perform different types of movement (e.g., detaching from an airplane, gliding down to water, sailing to land, and driving to a pre-designated location).

Once the detachable drone 100 is away from the moving vessel, the data capture system 120 attempts to communicate using a beacon based on the beacon data 150 (e.g., a conventional ping from a locator beacon). The beacon data may indicate different types of beacons (e.g., sounds, lights or a combination of these) for different situations (e.g., a flashing light at night time). With embodiments, the data capture system 120 assists search and rescue efforts locate the detachable drone 100 since the beacon that is emitted may be able to reach a larger area (when not at or below 20,000 feet underwater).

Thus, for crashes, the data capture system 120 ensures that the collected data 140 survives any impact. With embodiments, the data capture system 120 separates the detachable drone 100 from the moving vessel in the event of an emergency so that that search and rescue workers are able to find the detachable drone 100 and the collected data (which is critical information) even if the black box of the moving vessel is not found or is destroyed.

With embodiments, the data capture system 120 brings the collected data 140 to the surface (if the detachable drone 100 is under water). In certain embodiments, the data capture system 120 and may start delivering the data directly when an event (e.g., detection of a possible crash) occurs.

Embodiments combine the function of a traditional black box with the detachable drone 100. In the event of an emergency, the data capture system 120 detaches the detachable drone 100 from the moving vessel. The data capture system 120 stores the collected data 140, which may include details related to the navigation data and communications of the moving vessel. The data capture system 120 identifies how it will detach the detachable drone 100 and what is appropriate for transit of the detachable drone 100.

For example, events, such as a water landing, may have the detachable drone 100 detach and float to the surface; whereas, a mid-air collision/explosion may cause the detachable drone 100 to glide, parachute or fly to ground level. Once the detachable drone 100 is in an accessible location (i.e., is retrievable), the data capture system 120 transmits a beacon. In addition to electronic transmission, the data capture system 120 may contain radio signal reflecting material to assist in locating the detachable drone 100. With embodiments, the accessibility of the detachable drone 100 and its capacity to move itself may assist in locating the host vessel.

With embodiments, the detachable drone 100 is attached to the exterior of the moving vessel (e.g., a conventional aircraft or boat). Once a trigger event (e.g., an emergency event) is identified, the data capture system 120 starts the detachable drone 100 on a journey to deliver the collected data 140 (e.g., to search and rescue workers).

With embodiments, the destination of the detachable drone 100 may be predetermined locations that are determined before the moving vessel starts its trip. Thus, the location to which the data capture system 120 moves the detachable drone 100 is predefined. For example, if the detachable drone 100 were underwater (after being detached from a naval vessel or submerged airplane), the data capture system 120 would move the detachable drone 100 to the surface of the water by, for example, buoyancy and underwater navigation or by deploying a flotation device. Once on the surface of the water, the data capture system 120 begins to ping over radio frequency and, if possible, maneuver the detachable drone 100 to the nearest predetermined location (e.g., for pickup by a search and rescue worker).

With embodiments, a solar powered cell is incorporated into the detachable drone 100 to allow it to migrate to the predetermined location over a series of flights. With the inclusion of a solar cell, the data capture system 120 may to pulse on radio frequencies for more than the month that a conventional beacon typically maintains. Also, the higher energy and position of the detachable drone 100 allow for a greater range for the beacon.

FIG. 2 illustrates, in a flow chart, operations for monitoring a moving vessel in accordance with certain embodiments. Control begins at block 200 with the data capture system 120 monitoring a moving vessel to which detachable drone 100 is attached to capture data. In certain embodiments, the moving vessel has various that are monitored. In block 202, the data capture system 120 stores the captured data. In certain embodiments, the captured data transmit provides information about a failure (e.g., a catastrophic failure) or an impending destruction of the host vessel.

FIG. 3 illustrates, in a flow chart, operations for delivering captured data in accordance with certain embodiments. Control begins at block 300 with the data capture system 120 identifying an event that triggers detachment of a detachable drone 100 from a moving vessel. For example, the event may be a decrease in air pressure of the moving vessel, may be a sudden change in direction of the moving vessel, may be detection of excessive heat (e.g., due to a fire) of the moving vessel, may be detection of malfunctioning parts (e.g., landing gear), may be breaks in certain thresholds (e.g., a steep delta in altitude or a very low value outside of the typical flight path), may be manual ejection (e.g., by pilots), etc. That is, the data capture system 120 performs analysis on the data being captured to determine when to detach the detachable drone 100.

In block 302, the data capture system detaches the detachable drone 100 from the moving vessel. In block 304, the data capture system moves the detachable drone 100 to a predetermined location. In block 306, the data capture system transmits a beacon based on beacon data. In block 308, the data capture system, in response to a request for data, delivers data collected from monitoring the moving vessel. In certain embodiments, a code (e.g., a password) is provided by a user to the data capture system 120 to access the captured data. In other embodiments, the data is encrypted, and a key is required to decrypt the data. The request for data indicates that the detachable drone 100 has been located. Delivery of the data may include displaying the data on a computer screen, emailing a report of the data, printing the data to a printer, saving the data to a file in a file system, etc. With embodiments, the data capture system 120 stores the data (e.g., a backup copy) to another device, such as a node in a cloud or other network.

In certain embodiments, multiple detachable drones, each with a different data capture system, may be attached to a moving vessel. The different data capture systems may each detach based on a different set of conditions.
